Abstract: Examples disclosed herein relate to determining the shape of an object representation. In one implementation, a processor determines contours of a silhouette of an object representation above a contour degree threshold, where a contour degree is determined based on the area of the contour with respect to itself. The processor may identify a shape type of the object representation based on a comparison of the determined contours to shape definition information.

Abstract: An identification mark may have a calibration color, a predetermined authentication color, and a predetermined difference between the calibration color and the predetermined authentication color that is associated with a product; and a visual code with a mechanism that identifies the predetermined difference.

Abstract: A corrected optical property value of an optical property of interest captured within a digital image is determined. A search query based on the corrected optical property value is determined. A database is searched using the search query to determine search results for the search query that have appearance attributes with optical properties at least similar to the corrected optical property value.

Abstract: Examples relate to providing spatial analysis using attribute graphs. In one examples, there are a number of spatial points that each represent characteristics in a dimensional space. Non-data points are generated in the dimensional space, and a Delaunay triangulation is performed using the spatial points and the non-data points to generate a plurality of edges, where interior points of the plurality of non-data points that are in an interior space of the plurality of spatial points are excluded from the Delaunay triangulation. Next, spatial edges from the plurality of edges that each connect a spatial point that is connected to a first mixed edge to another spatial point that is connected to a second mixed edge are identified, where the spatial edges are used to generate a robust contour of a cluster of the spatial points.

Abstract: A system including a memory to store instructions and initial color representations and a processor to execute the instructions in the memory to reference a database having a set of lexical color classifiers, transform each of at least a pair of initial color representations to color values associated with the set of lexical color classifiers, and generate a relative similarity measure related to the at least a pair of initial color representations based on the color values associated with the set of lexical color classifiers.

Abstract: An apparatus for backing up a digitally stored image includes a substrate on which the image and digital restoration data corresponding to the digitally stored image are printed on the substrate. The apparatus may be scanned to restore the image printed thereon to its original digital form.

Abstract: A method for producing a customized print includes determining a color of at least one feature of an object, where the object is imaged with a reference color chart. A color palette is selected based on the at least one determined feature color and a print is generated based on the selected color palette. A system for producing a customized print is also described.

Abstract: A device captures a digital image of a color of interest and a physical color calibration chart. A corrected color value of the color of interest is determined based on the physical color calibration chart and the color of interest as captured within the digital image. A selected color value for the corrected color value is determined, as a closest color value within a predetermined color space or as a spot color value within the predetermined color space.

Abstract: The present disclosure related to acquisition of color calibration charts. In at least some examples herein, an image of a calibration color chart is processed. A lighting condition of the color calibration chart may be automatically determined.

Abstract: A system and method is disclosed for managed distribution of publication assets. The method discloses: protecting a set of assets, retrieved from the server system, in a publication component; transferring the publication component with the protected assets from the server to client computers; previewing the publication component on one client computer based on the set of protected assets; and producing the publication component on another client computer based on the set of protected assets. The system discloses: a server system; a publication management module for: applying a set of fonts to a publication component; and transferring the publication component with the protected fonts from a server to client computers; a preview module for previewing the publication component on one client computer based on the set of protected fonts; and a production module for producing the publication component on another client computer based on the set of protected fonts.

Abstract: A method of extracting a color palette includes receiving in color attribute values of corresponding a image elements representing an image, transforming initial color attribute values to lexical color classifiers of the corresponding image elements, clustering the image dements based on the lexical color classifiers into clusters of image elements, and generating a color palette having color regions, each color region corresponding to a color associated with a cluster of image elements.

Abstract: A target and a method to use the target to determine the translucence of media is disclosed. The target has a first region and a second region. The first region comprises a color chart. The second region comprises a test pattern that is covered by the sample media when the sample media is loaded onto the target. The test target has a first area and a second area. An image of the target loaded with the sample media is used to determine the translucence of the sample media. The color of the media over the first and second areas of the test target are matched to the nearest color patches in the image of the color chart. The estimated actual colors of the media over the first and second areas of the test target are determined using the known colors of the nearest color patches. The translucence is determined using the difference between the estimated actual colors of the media over the first and second areas of the test target.

Abstract: The present disclosure relates to color calibration chart acquisition. In an example, a video acquired by an imaging device may be processed. The video may be analyzed to automatically detect a reproduction of a color calibration chart. Upon detection of a reproduction of the color calibration chart, it may be determined whether color calibration chart reproduction quality is within a selected quality threshold. Upon determining that color calibration chart reproduction quality is not within a selected threshold, user feedback may be provided, via the imaging device, to dynamically guide the user to make adjustments in the video acquisition in order to obtain a color calibration chart reproduction within the selected quality threshold.

Abstract: In the present disclosure techniques related to display of device independent color differences are described. In examples, a color comparison graphical user interface (GUI) is operated. The GUI displays a color of a sample object. Further, the GUI displays a color of a reference object. Further, the GUI displays a device independent color difference between the sample color and the reference color.
